As I was trying to say before, I am using to raise scrapbooking table to ease strain on back. Occasionally need to stand and bending over low table ... ouch! Also cannot sit for long periods of time bent over table ... this solved my problem. To work at kitchen counters was not a solution. Try it ... works great ... and very portable ... and versitle!

We used this item for raising a cedar chest with a 2" clearance up far enough that the heat from the wall vent would not scorch the underside of the chest. We re-directed the air flow with the vent extender unit to put the warm air out in the middle of the floor instead of under the chest by the wall under the window. The ears on the corners of the blocks did not allow proper positioning of the legs of the chest. Knocking the corner ears off was reasonably easy after I learned how the were put on. I used mounting tape to keep the chest from sliding off of the blocks.
